Post subject:  Hope the bad luck is over for a bit
To answer the last question:
I would guess it is somewhere between 9.75 - 10, but I cannot confirm.

I never cc'd the heads or anything like that.

Clutch explosion update / pics
Over the summer I was making a pass at test n tune at Pittsburgh, and on the first run that night I went to shift and the borg and beck 10" press. plate let go during a 6200 RPM shift from 1st to 2nd.

The pictures detail what is left of the clutch, press. plate, starter, and Bellhousing.

I also have some damage to the floorboards and I need to replace the engine block as The ears of the block also got broken off.
Luckily, I was not hurt, as the bellhousing and floorboard took the impact. I have all new Mcloed Clutch Press. plate and Flywheel.
I am still searching for another cast iron a-833 bellhousing.
If anyone has anylead on one, let me know PM me or email -
gocar1@netzero.com

I am also working with the Cox brothers on making a Real Deal Steel Bellhousing - It will be heavy - but it is a much better alternative to blowing up flimisy aluminum ones or rare cast iron pieces. It will retain the original starter location - That is the main reason I did not use a 340 scatter shield - I like the stock look too.

Here are some pics of the engine while it gets put together.


I Added A new explosion proof clutch, 1.6 roller rockers, Valve reliefs in pistions to allow 1.6 rockers, and Lou, I am re- degreeing the MP .528" cam lower towards the 100* mark as per your suggestions.
I also Had my dutra Hyper Pak Extude honed. It's as smooth as a show car's paint job inside there.
Pics Are Below:

I am still working on pounding / massaging the floor back to it's pre pressure plate disaster shape.

I probably will paint and detail under the hood too.



Thanks,
Greg

Thanks v2k -

I really do not know how much I totally have into the engine,

It is the third one I have had in there - I still have the original #'s matching block with 69,000 on it - I pulled that 2 years ago, over the years I have gone throught different cams, headers and carbs, I had to invest almost 900 into this ( third ) engine - That is just the short block, after the second one got wiped out from the clutch explosion.

I dont really know how much horsepower or torque it makes.


I just want to go a bit faster at the strip and try not to break stuff.

do you have any idea what caused your clutch to make it blow like that?

It wasnt designed for 6200 rpm's it really was a matter of time - Cast iron pressure rings will not turn 6200 for long without exploding.


If had known then what i know now I would never had run it in a race condition. - Street would be fine. Other folks had the same problem with the 10" chrysler plate.

Greg, for a good bellhousing you can always get an adapter plate from AndyF and run a Lakewood for a small block. :shock:

Sorry,

Can't say that I ever have.

When are they held?
I usually go to Pittsburgh Raceway Park - It's about 20min from my house.

If I break somethin, I can Make it home and grab the trailer and be home before 1.


Are you located Near Zele??

Just got back from the Columbus Race, and I did not win any rounds, But I am pleased with the cars' performance.

My best time was a 15.285

The long hours of winter wrenching paid off.
After the big Clutch explosion I upgraded a few things.
- Added 1.6 Roller Rockers
- Had The Dutra HyperPak Intake ExtrudeHoned Info Here
- Swapped the 4 speed with 4th Gear being 1:1 for an o/d unit where 3rd is 1:1

I will be going back to the Four speed Box for the pittsburgh Race - Hope it gets into the High 14's

See you at Pittsburgh or Carlisle!

Thanks Slantzilla,

I will be driving to carlisle this weekend with the 4.10 rear chunk and the .73 overdrive which yields a 2.99 Final drive ratio.

I will post Mpg Stats after the trip.


When I return home I will pull the 833 OD for the 833 Four speed with 1:1 Top cog.

I went to test n tune last week, but I had some voltage regulator and alternator problems so No real Runs were made.

I hope to be in the 14's with my 833 Four speed 1:1 Box.

This is with a full interior etc!.


Thanks, Greg

Bummer! :(

What's with all the electrical problems. Cox, You, and I swear that the problems with the aspen are electrical as well. Something was in the air out in columbus doing bad things.

Sounds like you've got a lot to do. Have a great time at carlisle, but again, this year I won't be able to make it. Instead of 1 car, I've got 3 to prepare for racing this month and time is running out.

14's will be wild! Your car looked great at columbus. None of the other slant six race cars I've seen in person are as fit to show.

Well Came Back form carlisle and With the O/D and 4.10's I got 21 MPG with the HyperPak Intake. That's averaging 70 Mph.

Well I will be removing said Overdrive and Reinstalling the four speed 833 with 1:1 Top Gear.

I also won an award with the car, A celeberity Pick.


It was a fun time. See you at Pittsbugh Chrysler classic.
